Police have discovered a cannabis factory with an estimated street value of £2.5m inside a redundant MOT testing station in Telford.
A man held on suspicion of the production of cannabis has been released under investigation.
Det Insp, Andy Bailey said: “It is likely that huge investment has been made in the setting up of this venture and it is extremely satisfying to know that all of the cannabis and equipment we have found will now be destroyed.
“Cannabis continues to be one of the most commonly used drugs in the UK and the impact it has on our communities should not be underestimated.
“We will continue to tackle reports of drugs production and supply across the region, and members of our community play an important part in this, through the information they provide.”
